About these units

Square Yard (yd²)

US & ImperialCurrent unit

9 square feet (0.8361 m²). Used for carpet, turf and land in the UK and India (where it is called a gaj).

Branches and rods lie behind this unit. The word yard comes from Old English gerd or gyrd, meaning a staff or measuring rod, and it first appears in the late seventh-century laws of Ine of Wessex, where a yard of land was a tax unit. Where its length came from is uncertain: pacing, the cubit and the arm of King Henry I have all been suggested. A square yard is simply a square of that length on each side.

After the 1959 agreement among six countries fixed the yard at exactly 0.9144 meter, the square yard became exactly 9 square feet, 1,296 square inches or about 0.836 m². It is used across the English-speaking world, notably in the United States, United Kingdom, Canada, India and Pakistan. In northern India it is called a gaj, and in Pakistan a gaz, and house plots there are often quoted in it. In the US and UK the yard, divided into eighths, is also how cloth is bought, so the square yard suits flooring and fabric in the same breath.

1 square yard = 0.83612736 square meters (exactly).

Arpent (North American) (arpent)

French (Ancien Régime)Historical unit (no longer in standard use)Approximate value

About 3,419 m² (0.845 acre), a square of 180 French feet. Still used in Louisiana and Quebec land records. The older Paris arpent was larger, about 5,107 m².

Arpent probably descends from the Late Latin arepennis, half a jugerum, which may itself trace to a Gaulish word for the end of a field. French surveyors used it for land and forests, and the size changed from province to province. Wikipedia describes the Paris arpent as 220 French feet on a side, about 71.5 m, which gives roughly 5,107 square meters.

The smaller arpent of 180 French feet, about 58.5 m on a side, gives 32,400 square French feet, near 3,419 square meters or 0.845 acre. Wikipedia files this version under North America, where Louisiana grants usually fixed river frontage in arpents with plots 40 or more deep. Some states round it differently, to 0.84628 acre in Louisiana and 0.8507 acre in Arkansas and Missouri.

The figure used here is 3,418.9 square meters. Mauritius and Seychelles use yet another arpent, near 4,221 square meters, and Quebec land records still use the term.

1 arpent (North American) = 3,418.89 square meters (approximately).
